I’m with Hora. ignoring economy, i much prefer the feel of petrol cars (i’ve driven a variety of diesel cars, from my 205 to a bmw 330d… (though i have to say the bmw 330d was the exception to the rule, save for a small amount of lag from standstill) back to economy… if you ignore any fuel economy advantage of a diesel (which is getting smaller, and in the real world some cost more to run on diesel than petrol on equivalent models at todays fuel prices), a diesel car is more expensive to run – more parts to go wrong/replace at service (particulate filters, high pressure pumps, high pressure injection systems, turbos…)
Back to the OP, Lexuss (lexii?) are famous for reliabilty, smooth engines and the ability to go intergalactic on mileage.
*I currently run a 15yr old pug 205 1.8 normally aspirated diesel, though will be replacing soon with a 2 litre subaru legacy. I hope. 🙂
